[英]Error with importing pandas in python3 'TypeError: descriptor '__subclasses__' of 'type' object needs an argument'
[英]TypeError: descriptor '__subclasses__' of 'type' object needs an argument while trying to import rasa_core
試圖運行一個在我的本地機器上運行良好的程序,但在 AWS 上我得到: TypeError: descriptor '__subclasses__' of 'type' object needs an argument
。 我的 pip3 沒有升級到最新版本,但這應該不會導致問題,因為我已經下載了最新版本的 rasa_core。
嘗試使用 pip3 -u rasa_core 重新安裝 rasa_core,還嘗試使用 sudo 附加命令。 這是我得到的錯誤,有人可以幫忙嗎
